6 3/5 mi
1/5 x 6 = 1 1/5
2/5 x 4 = 1 3/5
3/5 x 2 = 1 1/5
4/5 x 2 = 1 3/5
add all of them up and you get 6 3/5
Answer:
(-3, -4).
Step-by-step explanation:
-4x + y = 8
x - 5y = 17 Multiply this by 4:
4x - 20y = 68 Add this to the first equation:
-19y = 76
y = 76/-19
y = -4.
Plug this into the second equation:
x - 5(-4) = 17
x = 17 - 20
x = -3.
CHECK this result in equation 1:
-4(-3) + -4 = 8
12 - 4 = 8
8 = 8 <------ OK.
We first need to find the difference between $70 and $49.
$70 - $49 = 21
Now we find out what percent $21 is of $70.
21/70 × 100 = 30%.
That means the discount is 30%!
Now we must find 30% of $100, which is $30.
Then we subtract $30 from $100.
$100 - $30 = 70$
22.50 as a fraction is 45/2. Happy to help. :)
